Verbena plant named ‘USBENA5122’

ABSTRACT

A new and distinct cultivar of  Verbena  plant named ‘USBENA5122’, characterized by its low and outwardly spreading plant habit; vigorous growth habit; numerous large bright red-colored flowers; and resistance to Powdery Mildew.

Botanical classification/cultivar designation: Verbena hybrida cultivar USBENA5122.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Verbena plant, botanically known as Verbena hybrida, and hereinafter referred to by the name ‘USBENA5122’.

The new Verbena is a product of a planned breeding program conducted by the Inventor in Hikone, Shiga, Japan. The objective of the breeding program is to develop new disease-resistant and high temperature-tolerant Verbena cultivars with semi-upright plant habit and attractive flower coloration.

The new Verbena originated from a cross-pollination made by the Inventor on May 5, 2000 of a proprietary selection of Verbena hybrida identified as code number VJL47-1, not patented, as the female, or seed, parent with a proprietary selection of Verbena hybrida identified as code number VJL46-2, not patented, as the male, or pollen, parent. The cultivar USBENA5122 was discovered and selected by the Inventor as a flowering plant within the progeny from the aforementioned cross-pollination in a controlled environment in Bonsall, Calif. on Jun. 24, 2001.

Asexual reproduction of the new cultivar by cuttings at Bonsall, Calif., since Jun. 27, 2001, has shown that the unique features of this new Verbena are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘USBENA5122’. These characteristics in combination distinguish ‘USBENA5122’ as a new and distinct cultivar:

-   -   1. Low and outwardly spreading plant habit.     -   2. Vigorous growth habit.     -   3. Numerous large bright red-colored flowers.     -   4. Resistant to Powdery Mildew.

In side-by-side comparisons conducted in Hikone, Shiga, Japan, plants of the new Verbena differed from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Verbena were not as upright as plants of         the female parent selection.     -   2. Plants of the new Verbena were more vigorous than plants of         the female parent selection.     -   3. Plants of the new Verbena were resistant to Powdery Mildew         whereas plants of the female parent selection were susceptible         to Powdery Mildew.

In side-by-side comparisons conducted in Hikone, Shiga, Japan, plants of the new Verbena differed from plants of the male parent selection primarily in flowering time as plants of the new Verbena flowered earlier than plants of the male parent selection.

The new Verbena can be compared to the cultivar, Temari Scarlet, not patented. However, in side-by-side comparisons conducted in Bonsall, Calif., plants of the new Verbena differed from plants of the cultivar Temari Scarlet in the following characteristics:

-   -   1. Plants of the new Verbena were more compact than plants of         the cultivar Temari Scarlet.     -   2. Plants of the new Verbena were more freely flowering than         plants of the cultivar Temari Scarlet.     -   3. Plants of the new Verbena flowered earlier than plants of the         cultivar Temari Scarlet.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used. Plants grown in 15-cm containers were used for the aforementioned photographs and following description. Plants had been growing for about ten weeks when the photographs and the description were taken. Plants were grown under conditions which closely approximate commercial production conditions during the winter in Bonsall, Calif. in a polyethylene-covered greenhouse. During the production period, day temperatures ranged from about 13 to about 35° C. and night temperatures ranged from about 10 to about 16° C.
